The hell I don't! LISTEN, KID! I've been hearing that crap ever since I was at UCLA. I'm out there busting my buns every night! Tell your old man to drag Walton and Lanier up and down the court for 48 minutes!

Because castor angles are fixed on a BMW MacPherson Strut? And the only way to adjust it is by adding castor plates?

Seriously? I had to answer that? It's like talking to my 4 year old daughter.

just answer if you know. is it adjustable and is it done when alignment is done. i read that is not adjustable. i want to verify from people that know or have the knowledge.

Seriously, why the sarcastic attitude from the both of you? Could there be a possible curiosity on my part (attempting to offer concise information to you) want to know what is the OP's rationale and motivation to the change or adjust these particular fixed points of the suspension; hence, my friggin' question before giving an answer.

This is not a typical question that comes up everyday in forums, so I was curious to know if there was a back story to your question. I do not know if OP's desired to adjust the slip angle or address a self centering action problem (too little or too much) at low speeds. Adjustment to the caster is not typically done.

No, but the average high schooler knows that McPherson type suspension does not allow adjustment to caster angles, not unless you use caster plates.

Besides, the reason why (I think) you are getting attitude is because you were already given the answer:

EDIT:
P.S.: Do not attempt to insult The HACK. He is one of the few people out here from whom you can actually learn something worth remembering!

I disagree -like I mentioned before- I was asking the OP his reason why. That's why I avoided your answer, I did not need to know the answer. Unlike you that assumes most people know what you know, well I don't presume most people know what I know; hence, why the simple question.

He asked the question to opens the forum, which allows us ask for follow up questions. I knew the answer, but I do see my error (I'm big enough to admit it) of not being clear to whom I should have addressed my question, which was not towards the Hack.

I was not being insulting. The two words have the two completely different meanings. I do agree he's knowledgeable, but does not give anyone the right to give sassy comments without reply back.

Caster on the E9x and E8x chassis is VARIABLE during the turn, unlike most strut suspended cars. For most cars we ship Vorshlag camber plates in the full-additional-caster position because most chassis need more caster and the only way to get it is to change the static caster. But the E90/E80 have dynamic caster provided by the multi link lower arm. We ship camber plates for those chassis in the no-additional-caster position as we feel they already have enough due to the unique suspension.
